ACSYNCA/B
Audio control packet synchronization data. Designates the sync mode
bits (asx, asy) as defined in SMPTE 272M (section 14.5) of channels 1/
2 or 3/4 of the audio control packet. The bits are selected by
“

AC34/12
Audio control packet channel pair select. When set HIGH, audio
control packet delay data for audio channels 3 and 4 is captured in
registers #Ah, #Bh, #Ch and #Dh. When set LOW, audio control packet
delay data for audio channels 1 and 2 is captured in registers Ah, Bh,
Ch and Dh.
